unsigned char* values to hexadecimal [duplicate]

by

How about something like this:

unsigned char *pBuffer = (unsigned char *)pvaluefromClient //where valuefromclient is received from a client

int i, j;
unsigned char target[16]
for(i=0;i<32;i+=2)
{
   sscanf((char*)&pBuffer[i], "%02X", &j);
   target[i/2] = j;
}
